The Radiology Department of the Montreal General Hospital was testing a digital system for gastrointestinal examinations. The goal of the study was to evaluate its potential in clinical situations, with the purpose of complementing or replacing the old fluoroscopic system available at the moment. / The core of our study was to image 18 surgical specimens with gastrointestinal pathology utilizing 3 different techniques: high resolution shielded-cabinet, the Siemens digital system and the conventional analog hard copy system. / A skin dose exposure test was conducted by the department with the purpose of assessing the benefits of both the digital and the conventional systems. / We concluded in this study that the many advantages of the digital system--lower skin exposure, image reconstruction and manipulation, fast access to images, overcome its inferior resolution as compared with the analog hard-copy generation system.
